You caught your sister walking around the house pretending to be pregnant again. She's so annoying when she does that. She's a sweet sister though, as she notices you're a bit tired from a long day and brings you a glass of water. What you didn't know, though, was that she laced that water with an incredibly strong aphrodisiac that supposedly makes you cum huge loads repeatedly - and your sister wants to test that! She's so desperate for a baby that she'll do anything, and after that aphrodisiac, so are you! She blows your raging cock and you cum loads all over her tits. Then she sucks you off again and you fill her mouth up to the brim! But she's not through with you yet... You and your cock are a bit tired from coming twice already, but you're so messed up from that aphrodisiac that you don't even notice how hard she pounces on your hard on that just wont go away. She rides you deeply and you cum inside her while watching her perfect boobs bounce. Then, yet another cumshot explodes all over her belly and pussy as your previous creampie is still running out of her. Oh man, after this she's going to be prego for sure!
